St. Peter Sandstone, Illinois Basin

General Setting

The Illinois Basin is an elongate intracratonic basin located mostly in central and southern Illinois, southwestern Indiana, and western Kentucky (Collinson and others, 1988). It extends some 600 km northwest to southeast and 320 northeast to southwest. The greatest thickness of sedimentary fill is in southern Illinois and western Kentucky, where a maximum of 7,000 m of Paleozoic sedimentary fill occurs.

Information Search and Selection

The deeper portions of the Illinois Basin are the focus of this investigation because this area contains strata that are sufficiently deep, porous and permeable, and hydraulically isolated from fresh-water aquifers to make potential CO2 sequestration targets. Moreover, southern Illinois and western Kentucky are areas with major CO2 producers (fig. 1).

The subsurface of this area has been well studied, the research driven by the search for domestic and industrial water supplies, petroleum, and, to a minor extent, subsurface disposal of industrial liquid wastes. However, the majority of study has been associated with relatively shallow (fresh-water) aquifers and shallow (Mississipian) hydrocarbon-bearing horizons. There have only been a few brine-aquifer waste-disposal studies in the region (Bergstrom, 1968; Cartwright and others, 1981; Roy and others, 1988). Although these provide excellent, site-specific information, they do not provide information regarding spatial distribution of deep-brine-aquifer characteristics.

A number of potential porous, permeable and continuous sand units within the southern Illinois Basin area could potentially be used for CO2 sequestration. Some of these include the Cambrian Mount Simon, Eau Claire, Gatesville, and Ironton Sandstones, as well as the Lower Ordovician Gunter and New Richmond Sandstones. However, we chose to focus on the Middle Ordovician St. Peter Sandstone for inclusion in the GIS because this unit is a regionally continuous porous and permeable sandstone that is overlain by the thick, impermeable, regionally extensive, Maquoketa Shale Group, which serves as an aquiclude (Young, 1992a, b). The Mt. Simon Sandstone is also characterized for study in this area in the GIS.

The St. Peter Sandstone has been studied in the region for both hydrocarbon and liquid waste-disposal potential (Hoholick, 1980; Kreutzfeld, 1982; Zuppeman and Keith, 1988). There have been a number of regional studies addressing the hydrogeologic properties of the St. Peter Sandstone to the north in northern Illinois, Minnesota, and Wisconsin, where the unit is shallower and contains fresh water (Burkart and Buchmiller, 1990; Mandle and Kontis, 1992; Young, 1992a, b). Although these hydrogeologic studies provide some useful information about aquifer parameters, they do not include the central Illinois Basin region
